Once a help library has been created, it can be interrogated by an
application program through the HLP_HELP subprogram. The programmer
supplies the following four things:
- The call to HLP_HELP.
- A subprogram which handles one line of retrieved help text,
typically displaying it in some way.
- A subprogram which provides one line of interactive input.
- A subprogram which translates a help library name into a filename.
The HLP package includes a demonstration application TSTHLP.FOR,
together with subprograms HLP_OUTSUB.FOR, HLP_INSUB.FOR and HLP_NAMETR.FOR.
